Step by step explanation needed!!​

Answer:

(2r-3)-4=37

or,(2r-3)=37+4

or,2r-3=41

or,2r=41+3

or,2r=44

or, r= 44/2

hence , r= 22

Answer:

x=2y

Step-by-step explanation:

y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.

Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.

Answer:

2

Step-by-step explanation:

f(x) starts at the orgin, (0, 0), and g(x) starts at (0, 2)

With this information we can decide that k is 2 as it moved the line up 2

Definitely needs to serve some detention with Miss Trunchbull.

Answer:

exploration is the answer I got

Answer: the first one is irrational because it is a repeating fraction.

the third is square root of 7 is less than 14/5

the fourth is negative 5 over 6, negative 5, negative 31 over 6, negative square root 26

Step-by-step explanation:

You just need to multiply 3762 with 54

Answer:

x = 1

Step-by-step explanation:

I'm going to convert this to decimal to make it easier to type

Since x = 1, there is no need to include it in the equation

1/4 - 8 = -7.75 + 12 = 4.25

-0.75 + 5 = 4.25

Answer:

By simplifying both sides of the equation, then isolating the variable.

X=1

Step-by-step explanation:

1/4*1-8+12=-3/4*1+5

One option (that I would use):

Ignore the decimals and multiply 13 x 916.

    9 1 6

  x    1 3

 2 7 4 8

 9 1 6 0

1 1 9 0 8

OK, now take into account there were a total of three digits to the right of decimal points (3, 1, and 6), so your answer also needs three digits to the right of your decimal point.

Answer 11.908

Answer:

Step-by-step explanation:

ΔABD ≅ ΔACD    {A S A congreunt}

∠ADB ≅ ∠ADC   {CPCT}

∠ADB + ∠ADC = 180   {linear pair}

2∠ADB = 180

∠ADB = 180/2

∠ADB = 90

∠ADB = ∠ADC = 90.

So, now we can use Pythagorean theorem to find x

x² = 8² - 2²

   = 64 - 4 = 60

x = √60

Answer:

Step-by-step explanation:

Identity used: [tex]a^{2}-b^{2} = (a + b)(a -b)[/tex]

81 = 9*9 = 9²

a = x^2 and  b =9

Then again 9 = 3*3.In this way, (x² - 9 ) can be again factored

[tex]x^{4} - 81 = (x^{2})^{2}-9^{2}\\\\=(x^{2} + 9)(x^{2} - 9)\\\\=(x^{2}+9) (x^{2} -3^{2})\\\\= (x^{2} + 9}(x+3)(x-3)[/tex]

Step-by-step explanation:

9514 1404 393

Answer:

  60°

Step-by-step explanation:

The exterior angle is equal to the sum of the remote interior angles:

  100° = 40° +∠B

  60° = ∠B . . . . . . . . . . . . . subtract 40° from both sides

Step-by-step explanation:

Answer:

(-4 1/5) - (-13 1/10) = 8.9

If you want to EVALUATE IT than the answer is 107.42.

Step-by-step explanation:

Answer:

x = 120°

The triangle is an equilateral triangle and all the angles in an equilateral triangle equal 60°.

Straight lines have 180° angles.

180 -  60 = 120

It's a fraction. At the numerator we have : -5+9×4-2+(8-3)×6 = -5 + 36 -2 + 5×6 = -5 +36-2 +30= 31-2+30 = 29+30= 59

59/2 = 29.5 +3 = 32.5

Step-by-step explanation:

line A and D are parallel because they have the same koeficient 3=3

line C is perpendicular to line A because

k1*k2=-1

3*(-1/3)=-1

which is a true statement

Answer:

a) Line D is parallel to line A

b) Line C is perpendicular to line A

Step-by-step explanation:

Line A has a slope of 3 and y intercept of 6

Line C is perpendicular to A as perpendicular lines have negative reciprocal slopes. Slope of C is -1/3

Line D is parallel to A as parallel lines have identical slopes but different y intercepts. Slope of D is 3 and y intercept is -1/3

Line B mirrors Line A over the y axis. It's slope is the negative of A and it has an identical y intercept.
